The invention relates to a technique whereby karaoke music and lyrics, which have been digitalized with the help of MIDI data, are transmitted by public telephone line for reproduction on a terminal unit. Associated dynamic images are, on account of the volume of data required, stored independently of the music and lyric data within the terminal unit itself and retrieved and extracted with the help of codes which are written into the data in advance. The dynamic images and the lyrics are finally mixed and output to a visual display medium.

Conventional karaoke devices simply show lyrics on screen. This invention displays not only lyrics but also data useful for the enhancement of the singer's presentation such as the strength of the vocals and the pitch. More precisely, vocal data, which indicates the special requisites of a specific vocal rendition such as its strength and pitch, and the current lyric position indicator, which marks the current position in the lyrics, are correlated with the music data to which they correspond and then stored in memory. The said vocal data and current lyric position data are then read out of memory and each block of vocal data is displayed on the screen of a visual display medium a little in advance of the music to which it corresponds while the current lyric position within said block of vocal data is indicated in time with the music. Moreover, the strength and basic frequency of an actual vocal rendition can be detected and compared with the stored vocal data.

An idle time communication device in which communication windows are created during the transmission of broadcast data from a center unit to a user's home device, the windows being designated to augment the data transmission function by enabling one-to-one bidirectional communication between the center and the user's home. The invention assumes the prior existence of a communication device for the transmission of broadcast data from the independent center through the telephone network to the user's home and achieves its object of one-to-one bidirectional communication between the center and the user's home through the use of packet communication which is carried out during the idle time on the telephone network, which connects the switching system of the local telephone exchange with the telephone in the user's home. The invention enables both the transmission of download data from a control unit to a specified terminal and the transmission of upload data from a specified terminal to a control unit without confusion between terminals in either case. This enables, for example, (a) a control device to transmit download data to a specified terminal and for the due arrival of the download data to be confirmed at the center by the return of upload data from the terminal, (b) the center to receive music requests and instructions in the form of upload data from a terminal, and (c) the creation of a protocol that will enable error-free communication to be carried out between the control device and terminal.

The invention provides an indication for a karaoke singer of that music in the karaoke music library which would be best suited to the singer's own vocal characteristics. For the purpose of providing this indication, the singer's voice signals are first of all sampled at suitable intervals and the sample waveforms converted into specimens made up of digital values. A body of data relating to vocal characteristics is at the same time stored in the device, each item of said data being assigned its own code. When the above specimens are input, they are compared with the stored data by an evaluation means which then identifies the items of data that resemble each other most closely. The codes which are incorporated into the data items so identified are then treated as retrieval items and any library data with a matching code for each of a plurality of pieces of music is duly retrieved and the music with the matching code is extracted.
